DUMPING-GRATE.

To all whom if may concern:

Be it known that I, WILLIAM W. Lnwis, a citizen of the United States,residing at Garnet, in the county of Kanawha and State of West Virginia,have invented a new and useful Dumping-Grate; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a new and useful grate.

Tt is the object of this invention to produce a device of this design,in which simple, efficient, practical and desirable features ofconstruction are involved.

One of the features of the invention resides in a grate, which may beeasily manipulated, so as to dump the fire, and shaken to remove theash.

Another feature is the provision of a lock to hold the grate in ahorizontal position.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

ln the drawings z--Figure 1 is a longitudinal sectional view through afire box of a range, showing the improved grate as applied. ,Figz 2 is across sectional View on line 2-2 of Fig. 1. Fig. 3 is a detailed view ofthe means for operating the grate. and also the locking means for theoperating means. Fig. 4 is a detail view of a portion of the grate,showing the connection of the lever 14 therewith.

Referring more essentially to the drawings, 1 designates the frame forthe side grate bars 2, the latter being connected to the bars 3 and 4 ofthe frame 1. Projecting inwardly of the fire boX, and from the frame lis a supplemental frame 5, the end and longitudinal bars of whichare'connected by dove-tailed joints 6. Each of the end bars of thesupplemental frame is provided with an aperture 7. Mounted in theapertures are the pintles 8 of the tilting grate 9. @ne of the pintlesof the tilting grate is formed with a rectangular portion 10, which isarranged in the opening 11 of the arm 12. This arm l2, by thisconstruction works rigidly with the tilting grate, and is disposedSpecification of Letters -'al:ent.

between one of the end bars and the grate. l-)ivoted to the lower end ofthis arm, as at 13 is a lever 14. This lever 14 passes through anopening in the lower bar of the frame 1, and is provided with a notch14a. The opening is denoted by the numeral 15. Pivotally mounted as at16 to the lower bar of the frame is a latch 17, adapted to engage thenotch of the lever, to hold the tilting grate in a horizontal position.Vhen it is desired to tilt the grate, in order to dump the lire, orremove the clinkers, the latch is raised from engagement in the notch,and subsequently the lever is reciprocated. @ne end of the tilting grateis formed with a shoulder 1S, which contacts with the lever 14 to limitthe grate in its pivotal movement in one direction7 that is, when thegrate is being rattled, so as to only stir the lire. In rattling orshaking the grate, the lever is reciprocated slightly, in other words,not enough to dump the fire. In this way the body of the lire is notlost. The shoul der on the tilting grate limits the same in its movementin the other direction.

From the foregoing it will be noted, there has been devised a novel,simple, and practical tilting grate, adapted mainly for use inconnection with ranges and the like.

Coupled to the lever as at 19 is an arm 20, which is adapted to be swungdownwardly, when the grate is at rest. This arm is designed for thepurpose of operating the lever 14.

The invention having been set forth, what is claimed as new and usefulis ln combination with a fire-box having vertical front grate bars, saidfront grate bars being provided with a lower bar and having a laterallyprojecting frame arranged horizcntally in the fire-box. of a tiltinggrate having a pintle at each end journaled in each end of said lateralframe, one of said pintles having a rectangular portion. an arm havingan opening fitting` the rectangular portion, said arm being held on therectangular portion between one end of the tilting grate and one end ofthe lateral frame, and a lever mounted in the lower bar of the frontgrate bars and connected to the lower end of said arm for rocking thetilting grate,

the tilting grate having a shoulder alined In testimony whereof I havesigned my with said lever so as to engage the lever name to thisspecieation in the presence of when the grate is rocked7 to limit thesame two subscribing witnesses. Y

in its pivotal or rocking movements, and a VILLIAM W. LEl/VIS. memberpivotecl on said lever for manipu- Nitnessesz loting the latter wherebythe tilting giate JAMES N. SCOTT,
